Almost none of it is. ABS is one of the most common

you'll find others, including PVC, glass-filled nylon, polypropylene,
HDPE, and more.
There are some filled plastics used during the 90's (probably ABS)
with what seems to be a too-high proportion of filler. These tend to
be almost fragile now, shattering into many small pieces when
subjected to any force at all. I've resorted to fiberglass mesh and
polyester resin to repair and reinforce these, finishing up with a
coat of paint. Doesn't look bad, but is hardly original.
I played with the idea of making a mold from the old pieces and using
acrylic resin to cast a duplicate, but there were too many details
(mounting bosses, ribs, tabs, etc.) on both sides to assure success.
